摘要: 550 kV线路融冰开关安装在户外,当高压输电线路需进行融冰处理时,融冰开关很可能也处于覆冰状态,因此满足不同工况的平衡性能设计非常重要。根据融冰开关技术参数要求,对550 kV大容量融冰开关的结构进行设计,并在此基础上对融冰开关不同工况下的平衡性能进行设计与校核。试验结果表明,该550 kV大电流融冰开关的平衡性能满足正常操作及20 mm厚度覆冰工况下的操作要求,具有普遍适用性。

Abstract: The ice melting disconnector of 550 kV line is installed outdoors. When the high-voltage transmission line needs ice melting treatment, the ice melting disconnector is also likely to be in icing state. Therefore, it is particularly important to meet the balance performance design under different working conditions. According to the requirements of product technical parameters, the structure of 550 kV high-capacity ice melting disconnector is designed. On this basis, the balance performance of ice melting disconnector under different working conditions is designed and checked. The results show that the balance performance of the 550 kV high-capacity ice melting disconnector meets the operation requirements under normal operation and 20mm icing conditions, and the balance performance design method adopted is generally applicable.

Key words: ice-melting disconnector, high capacity, balance performance
